intravenous nutrition

Intravenous nutrition, also known as total parenteral nutrition (TPN), is a method of providing essential nutrients directly into the bloodstream through a needle or catheter inserted into a vein. It is used when the digestive system cannot absorb nutrients properly due to illness, surgery, or medical conditions. TPN supplies a carefully balanced mixture of carbohydrates, proteins, fats, vitamins, and minerals, ensuring the body receives the nourishment it needs to function, heal, and maintain strength, all without relying on eating or digestion.
